Summary
Chapter 7 of the Class 2 Maths NCERT textbook (Joyful Mathematics), "Rani's Gift", introduces young learners to measurement through hands-on activities covering length, weight, and capacity using everyday objects and non-standard units.
- Measuring Length with Handspans — The chapter opens with a story about Raja Jagdeep who asks for a bed 10 handspans long, but different people measuring with their own hands get different answers (8 or 14 handspans). This shows children why a standard unit of measurement matters.
- Comparing Lengths of Objects and Paths — Children practice estimating and measuring the lengths of classroom objects like a desk, blackboard, and window using their textbook as a measuring tool. They also compare different paths between two points to find the longest and shortest routes.
- Measuring Height Using Blocks — The chapter uses stacked blocks to measure the height of toy animals like a giraffe, monkey, and elephant. Children fill in the number of blocks each toy is tall, building the idea of using a repeated unit to measure height.
- Comparing Weight: Lighter and Heavier — Using vegetables like pumpkin, muskmelon, capsicum, and carrot, children compare which objects are lighter or heavier. They learn to arrange objects in increasing order of weight and are guided to make a simple balance using a paper cup, thread, and hanger.
- Measuring Capacity with Glasses — The chapter introduces capacity through a nimbu pani (lemonade) recipe: 1 glass of water, 1 spoon of sugar, 2 spoons of lemon juice, and a pinch of salt makes 1 glass. Children scale the recipe up to 3 glasses, and compare how much water different bottles can hold.
Key points & formulas
- 01In the chapter story, the same bed measured 8 handspans by one person and 14 handspans by another because people have different hand sizes.
- 02Children measure classroom objects (desk, blackboard, window) using their textbook and record estimated and actual lengths.
- 03Height can be measured by stacking blocks — for example, the giraffe's height is given in a number of blocks.
- 04Vegetables like pumpkin, muskmelon, capsicum, and carrot are compared by weight using the terms lighter and heavier.
- 05Children can make their own balance with a paper cup, thread, and hanger to compare the weight of two objects.
- 06The nimbu pani recipe for 1 glass uses 1 glass water, 1 spoon sugar, 2 spoons lemon juice, and a pinch of salt.
- 07Capacity is explored by comparing how many glasses of water fill different bottles.
Frequently asked questions
01What is Chapter 7 of Class 2 Maths Joyful Mathematics about?
Chapter 7, 'Rani's Gift', is about measurement. It covers length, weight, and capacity through stories and activities using everyday objects.
02What story is used to introduce measurement in this chapter?
The chapter tells the story of Raja Jagdeep who wanted a bed 10 handspans long. When different people measured it with their own hands, they got different numbers (8 or 14 handspans), showing that handspan size varies from person to person.
03What does the handspan story teach children?
It teaches that using your own hand as a measuring unit can give different results for different people. This is why a standard unit of measurement is needed.
04How do children measure objects in the 'Let us Do' activity?
Children use their textbook to measure objects like a desk, blackboard, and window, recording both their estimated length and the actual measured length.
05How is height measured using blocks in this chapter?
Children look at toy animals such as a giraffe, monkey, and elephant and count how many blocks tall each one is when blocks are stacked next to it.
06Which vegetables are compared by weight in the chapter?
Pumpkin, muskmelon, capsicum, carrot, bottle gourd, cauliflower, and watermelon are compared. Children identify which is heavier or lighter than others and find the heaviest and lightest.
07How can children make their own balance at home?
The chapter explains how to make a simple balance using a paper cup, thread, and a hanger. Children can then place objects like an eraser, ball, or pencil on each side to see which is heavier.
08What ingredients are used to make nimbu pani for 1 glass?
For 1 glass of nimbu pani, Raghu uses 1 glass of water, 1 spoon of sugar, 2 spoons of lemon juice, and a pinch of salt.
09If Raghu wants to make 3 glasses of nimbu pani, how much of each ingredient does he need?
He needs 3 glasses of water, 3 spoons of sugar, 6 spoons of lemon juice, and 3 pinches of salt — three times the amount needed for 1 glass.
10What is the capacity activity in this chapter?
Children find out how many glasses of water fill their own bottle and a friend's bottle, then compare whether the two bottles hold equal, more, or less water.
11What is the 'Pumpkin's Chaupal' activity about?
In this activity, children look at a picture of vegetables and use words like lighter and heavier to compare them. They fill in blanks to say which vegetable is heavier or lighter than another.
12How does the 'Fruits in the Park' activity work?
A watermelon and some mangoes sit on a see-saw. Children figure out how many mangoes balance the watermelon, and then work out how many coconuts would balance the watermelon if 1 coconut equals 2 mangoes in weight.
13What project work is given for measuring length at home?
Children are asked to measure any wall of their house, the length of their bed, and the length of a door using any tool they choose, such as an eraser, blocks, or a pencil.
14What is the jal tarang project in this chapter?
Children arrange 5 to 7 similar glasses or bowls, fill them with different levels of water, and gently tap a spoon on each to hear how the sound changes — exploring capacity while making a simple musical instrument.
